SYNOPSIS FOR THE GULF OF AMERICA
1015 PM EDT TUE AUG 18 2026
SYNOPSIS
HIGH PRESSURE WILL PREVAIL ACROSS THE GULF WATERS
THROUGH THE FORECAST PERIOD. A WEAK PRESSURE PATTERN WILL SUPPORT
MOSTLY GENTLE TO MODERATE WINDS ACROSS MUCH OF THE BASIN. A
DIURNALLY INDUCED SURFACE TROUGH WILL GENERATE FRESH TO LOCALLY
STRONG WINDS NORTH AND WEST OF THE YUCATAN PENINSULA EARLY EACH
EVENING. THESE WINDS WILL SPREAD WESTWARD AWAY FROM THE YUCATAN AT
NIGHT AS THE TROUGH MIGRATES INTO THE SW GULF. SLIGHT TO MODERATE
SEAS ARE EXPECTED THROUGH THE FORECAST PERIOD.
